RUBIDGE, or PITTSFIELD, massacnusnr'rs, ASSIGNOR, BY MESNE ASSIGN- mnnrs, T0 ummawoon ELLIOTT FISHER COMPANY, A CORPORATION or DELAWARE TYPEWRITING MACHINE Applicationflled November 14, 1929. Serial No. 407,251.

My invention relates to typewritingmachines, more particularly to typewritmg machines intended to write upon a number of superposed continuous work-sheets or webs, and has for its object the provision of an improved typewriting machine of this. character.

' give in that from the plies ofthe My invention is especially related to typewriting machines provided to write upon superposed continuous sheets or webs which are intended to be torn olf in sections from the body of the web so that each section when the typewriting thereon has been completedwriting on one work section had been.com-.

pleted, it was necessary to remove the carbon sheetsindividually free from the completed work section and then interleave them with the plies of the succeeding section. This operation of removing the carbon sheets from the plies of the completed section a and of interleaving "them with those of the succeeding section required a considerable amount of time.

In an endeavorto overcome this difliculty, carbon carriers were provided and arranged to draw the carbon sheets back along the worksheet web so that upon the completion of one work section, interleaved'with the plies of the succeeding work section without their being removed work-sheet, This arrangement eliminated the necessity of removing the carbon sheets individually from the completed work section and of assembling them individually with the succeeding section. This remained true as-long as the carbon sheets were fresh but upon their beeoming worn it was necessary as before to remove them individually and to substitute new sheets. e

Moreover, this practice proved to be expenwhen it became necessary to a'ssemble new sheets, it was customary to pmthe carbon webs could be I sheets withdrawn from vide a complete fresh set in spite of the fact that often-times but a portion of the total number of sheets needed replacement. Thus, where both hectograph and carbon sheets were being used, the wearing ability of the hectograph, which is much inferior to that of the carbon sheet, determined the time at which new sheets were to be provided. Also, this practice proved to be a very expensive one because it was possible to use only but a portion of the carbon areas.

An .efi'ort was made to utilize substantially the entire carbon areas of the sheets by reversing the sheets in the work-sheet sectlons, but this resort did not prove entirely satisfactory because the operation involved considerable effort and time. v v 1 Thus, the aforedescribed arrangement possessed certain disadvantages inherent in the former practice in that it was necessary frequently to interleave fresh carbon sheets with the work-sheet web; the replacement, as before being determined by the qualityof the poorest wearing sheet. a

In carrying my invention into effect in one form thereof, I provide a carbon carrierto support rolls from which continuous sheets of carbon may be drawn. It will be understood that several continuous sheets of carbon may be woundon one roll and that several like rolls may beused. The number of sheets used and the number of'rolls employed will depend upon the number of worksheets being fed. to the platen of the machine and upon the kindsof carbon used. Preferably, the carbon carrier to theside of the line of movement of, the work-sheets to the platen. I provide suitable means for separating the carbon 7 the rolls and for guiding them crosswise of the line of movement of the work-sheets for interleavement with the work-sheets. Moreover, I provide suitable guiding means on the carbon carrier for directing the carbon sheets into the line of movement of the work-sheets.

In order to facilitate the interleavement' of the carbon sheets with the plies of the work-sheet web, I movably secure the latter iding means on the carrier so that the gui' g means for rolls will bemounted on the carbon each sheet may be readily moved from its working position to a remote position. The operator is thereby enabled to readily assemble each carbon sheet with its guiding means and to readily interleave the sheet with its respective work-sheets.

Suitable locking means are provided for each roll so that accidental unwinding of the carbon sheets will bepreventedl and so that the rolls may be released to permit the withdrawal of the carbon sheets for interleavement-and renewal purposes.

For a more complete understanding of my invention reference may be had to the accompanying drawings in which Fig. 1 is a perspective view illustrating a typewriting machine embodying my invention; Fig. 2 is a front elevation of the carbon carrier provided for the typewriting machine of Fig. 1; Fig. 3 is a side elevation of a portion of the typewriting machine; Fig. 4 is a perspective view of a portion of the carbon carrier illustrating certain structural details; Fig. 5 is a fragmentary View illustrating certain structural details; Fig. 6 is a fragmentary view illustrating certain structural details; and Figs. 7, 8,9 and 10 are diagrammatic views illustrating the manner in which the carbon sheets are interleaved with the plies of the worksheet web. 1

Referring to the drawings, I have shown my invention in one form in connection with a typewriting machine intended to write upon superposed work-sheets or webs which are arranged in sections so that when the writing upon a section has been completed, it may be torn off or detached from the body of the web. As shown, the typewriting machine comprises a framework 10 upon which the usual platen (not shown), and a carbon carrier table 11, over which the work-sheet web 12 is passed to the platen, are mounted. The platen is provided with the usual hand wheel 13 which is mechanically connected with the platen.

It will be understood that the platen will be journaled in a suitable frame which comprises side plates 14. These plates in turn are pivoted at 15 so that the platen may be swung up and down between itsoperative position and a web releasing position. The

' frame provided to thus s'upport the platen may be locked with the platen in its operative position by means of suitable hook arms 16 arranged to engage cooperating pins (not shown) mounted on the platen frame.

The platen carriage carries a front paper table 17 over which the leading form'sections of the work-sheet web 12 are passed This table is provided with the usual gauge arm 19 which together with the front table serves to support and guide the advancing end of the work-sheet web. The usual (gauge 20 is provided on the gauge arm for etermining the length of the work-sheet sections .to be severed. 1

It will also be understoodthat the platen carriage will be provided with a rear paper table and apron -(not shown) for guiding the web and carbons down around and in the front of the platen. In operation, the worksheet web 12 is led from the carbon carrier table 11 over the rear apron and table around the platen and up over the front table 17. The platen carriage is supported on the machine frame 10 for letter feed and return directions by means of the usual rail 23.

The carbon carrier table 11 over which the work-sheet web 12 is passed to the platen from the rear of the machine is mounted on the machineframe formovcmentwith the platen carriage in letter feed and return directions. As shown, this table is a substantially rectangular framework comprising a pair of substantially parallel side bars 24 which are interconnected at their'rear by means of an end bar 25 and at their front by means of a bar 26. Preferably although not necessarily so, these bars will pair of lugs 30 secured to the platen carriage.

It will be observed (Figs- 1 and 3) that each end of the front bar 26 is provided with a reduced axially extending portion 2611 which is received in an apertured upright portion 304 provided on the associated lug 30. The front end of the table, therefore, is rigidly se cured to the platen carriage so as to be supported thereby and also so that the letter feed and return motions ofthe carriage will be imparted to the table. Preferably, the rear end of the table will be secured against vertical motion, by means of a pair of L shaped clips31, each of which is secured to the table so that its horizontal arm projects beneath-the rail 27. g

It will be-understood that the plies of the work-sheet web 12, which is fed to the platen over the table 11 from the rear of the machine, will be interleaved with carbon sheets so that a plurality of'dupl'icate copies will be produced simultaneously the first copy of the work.

As has been pointed out, one of the features of my invention is the provision of means for carrying rolls of continuous carbon sheets on with the production of the carbon carrier table 11 and further, the

tached without disturbing the assembly of the remaining sheets.

As shown, I have provided a suitable carbon carrier mounted uponthe carbon table 11 and arranged for movement toward and away from the platen in the line of movement of the work-sheet web 12. The carbon carrier 35 comprises spools provided to support rolls 36 of superposed continuous carbon sheets 37, plate-like roll supports 38 and a suitable supporting carriage 39. I he spools 360 Fig. 6)

for the carbon rolls are each provide with a pair of spool-ends 36b. The s 001 ends are provided with projecting stu -like rods or pins 360 which serve to rotatably mount the rolls within U-shaped receivin and retaining grooves 38a provided in t e plate-like supports. Preferably, the rolls will be mounted on axes substantially parallel with the line of movement of the work-sheet web 12 tothe platen. It will be understood, of course, that the plates 38may be provided with a number of setsof these U-shaped grooves for receivfng a corresponding number of rolls.

The carriage 39 has a substantiall rectangular supporting frame 40 (Fig. 4) which is arranged to receive and support a frame 41. The frame 41 serves to mount the roll supports 38, which as shown are secured in pairs to the opposite end portions of cross members 42. Each support 38 is provided at its lower edge with an inturned ear or lu 386 which in the assembled carrier is suitab y secured to the cross-member. Each member 42 issuitably secured to the upper rectangular frame" 41 b means of an intermediate plate 43 (Fig. 4;, which is secured in cantilever fashion to the frame 41, suitable screw fasten- "ing means 44 serving to secure these members together. The plates 43 may be adjusted to various positions upon the frame 41 so as to accommodate work-sheet webs having different widths. j v

The lower supporting frame '40is mounted for movement; toward, and" away from the platen upon a pai'r'of guide and supporting rails 45 suitably secured as b means of the screw fastening means '46 ig. 4) to the parallel side bars 24 of the table 11. .As

shown, the frame 40 is provided with a pair of rollers 47 on each side, these rollers being shaped to receive the edges of the associate rails 45 to thereby support andguide the car bon carrier. a

Preferably, the upper frame 41. will be detachably secured to the lower supportlng frame 40 so that the upper frame together with the rolls and their supports may be readily removed from the machine. As shown (Figs. 2 and 4), the upper frame is provided with depending lugs 48 which are arranged when the upper frame rests upon the lower frame to be received in corresponding. apertures 49 provided in the lower frame. Each lug 48 is provided with a notch or recess 48a which is arranged in the anoved so as to be received by the corresponding recesses 48a, the frame 41 will be locked in place upon the frame 40. To remove the frame 41 from the machine, it is simply necessary to move the latches 50 to their releasing positions and lift the frame 41 from-the frame '40. i

It will be observed that each carbon roll is mounted within its spaced supports 38 on an axis substantially parallel with the line of movement of the work-sheet web and the carbon carrier so that the carbon sheets as they are withdrawn from the spool for interleavement with the plies of the worksheet web will be led transversely over the carbon carrier. It will be understood, therefore, that since the carbon sheets .are led over the carbon carrier at right angles to the line of feed of the work-sheet web, it is necessary to turn the carbon sheets at right angles so that when interleaved with the plies of the work-sheet web, the interleaved carbon sheets will move toward the platen together withdrawn from the rolls'into the line of movement of the work-sheet web, I provide a series of turning rods 51, one rod for each carbon sheet withdrawn. As shown, each rod has an angular shape and is mounted in the roll supports 38 so that when it is in its working position, a portion 51a of the rod will be positioned diagonally. across the crosswise path of movement of the carbon sheet withdrawn from the roll so that if the carbon sheet withdrawn from they roll be turned about the diagonal bar, it will be directed into the line of movement of the worksheet web.

I Each rod 51 is pivotally mounted in the supports 38 provided for the carbon rolls from which the associated carbon sheet is withdrawn, and preferably so that its pivotal axis will be parallel with the axis of the roll. For this purpose the ends of the angular rod 51 are provided with projecting portions 516 which in the assembled carrier are received by suitable apertures provided in the supports 38. The rods will be formed from a resilient material such'as phosphor-bronze or spring steel so that the rods may be sprung into position between the supports 38 and be secured thereto with the projecting portions 516 received in their associated apertures by the inherent resiliency of the rod. Preferably one of the projecting portions 51?) will be provided with a recess or notch 510, the end portion of the projection beyond the notch being formed at an angle with the main portion or the projection (Fig. 5). Y The recess and bent end portion are arranged so that when the rod is fpositioned in the plates 38, the outer edge the recess Wlll engage the outer side of its associated plate 38 (Fig.

5). It will be observed that by'reason of this construction the rods will 'be securely locked in their supporting plates. In order to remove the rod, it is necessary to move the unnotched end of the rod inward from its plate 38 (Fig. 5) and then draw it toward the right so that the bent end portion of the recessed end may .be withdrawn from its aperture. The path assumed by the unnotched projectin end of the rod during this operation is clear y shown by the arrow in Ft is desirable to separate the superposed carbon sheets as they are withdrawn from each roll and to guidethem to their res ective work sheet plies without fouling. or this purpose, I have interposed between the rolls and the ath of travel of the worksheet web a p urality of vertically spaced 'rod-like members 52. It will be understood that these rods will be suitably spaced and that each carbon sheet withdrawn will be passed over (or under) its rod so as to be directed substantially into the plane passed bebon carrier will be drawn toward the platen with thework-sheet web, and .it will also be understood, of course, that a sufficient length of the carbon sheets will have been withdrawn to form the multiple copies. Itis desirable, therefore, in order to prevent accidental unwinding of the carbon rolls to provide positive locking means for each roll. For this purpose, I have provided for each spool a suitable locking pin 53 which is mounted on one of the roll supports adjacent one of the spool-ends by means ofa supporting strip 53a. This strip will be formed from a suitable resilient material such -as phosphorbronze. As shown, the support 38 is pro-' vided with an aperture for each pin and throu h which the pin'projects so as to engage t e spool-end. Preferably and as shown (Figs. 2 and 6). the spool-end will be. provided with a plurality of apertures 54 arranged in a circle adjacent the peripheryof the head and the locking pin 53 will be positioned so that when its end will be projected into one of the apertures. To. release the roll it is but necessary to withdraw the pin from the aperture. This arrangement provides means for positively lockingthe carbon roll in any desired osition and for effecting a ready release 0 the roll.

f It is preferable .to guide the work-sheet web together with the interleaved carbon sheets from the rear of the machine to the platen. As shown, I provide a pair of guides 55 for the edges of the work-sheet. web at the rear of the machine and a similar pair 'of guides 56 for the edges of the work-sheet web and the carbon sheets at the front of the machine.

The. pivotal mounting of the guide rods 51 is a very important feature of my invention in that by reason of this construction it is ossible for the operator with but little efort to quickly interleave the carbon sheets with the plies of the work-sheet web.

The operation of interleaving the carbon sheets with their respective work-sheet plies will be readily understood by reference to Figs. 7*10 inclusive. (In these figures but threelplies of the work-sheet web 12 have been shown and accordingly but two carbon sheets with their associated rolls have been shown. It will beunderstood, of course, that the number of carbon sheets will be one less than the number of plies and furthermore that each roll of carbon may consist of superposed carbon sheets.

In order to interleave the carbon .sheets with the web plies, the lower carbon sheet, that is the sheet shown at the right of Fig. 7, is drawn from the spool crosswise of the carbon carrier under (in this case) its guiding. and separating bar 52. The spools, of

.course, will be unlocked during the interleaving operation. Then with the guide rods 51 for the upper carbon sheets swung upwardly (Fig. 7 from their working positions, the

lower carbon length is turned around and brought forward under its guide rod 51 to a'position slightly forward --of the carbon carrier'(Fig. 9) The arrows shown in Fig. 8 will make clear the path assumed by the carbon sheet during this operation. It will be understood that the guide rod 51 may be rotated aboutits axis to any suitable position most convenient for the carbon turning operation. 1

In like manner the carbon sheet for the next higher ply, will be withdrawn from its spool, passed under (or over) its guide bar 52 in order to bringit. into a plane substantially that of its corresponding work-sheet ply, and-then turned about its diagonal guide bar 51'. r

After the carbon sheets have thus been withdrawn and turned about their guide rods- 51 and with these rods in their respective positions shown in Fig. 8, the work-sheet web isdrawn forwardto a position slightly I.

forward of the carbon carrier (Fig. 9.). Then the u per sheets of the web'are raised so that the ower guide rod 51, together with the carbon sheet turned about it, may be moved downwardly to bring the carbon sheet into the plane of the lower work-sheet (Fig. 9). The upper ply is then lowered and the positioned next upper ide rod with its carbon sheet is tween the upper work-sheets (Fig. 10).

Likewise if there be more work-sheet plies, successively higher carbon sheets will be turned about their guide rods and be interleaved with their respective plies.

If the first fold of the web section is at the right rather than the left, as viewed in Figs. 7-10, the carbon carrier assembly will be detached from the carrier frame 40 and will be rotated through 180 horizontally and re placed on the carrier frame. The guide rods 51 will then be reversed so as to be positioned correctly to turn the carbon webs toward a the platen. It will be understood. that by .leaved with the work-sheet web, the web tothus reversing the roll carrier, the lower guide rods 51 and 52 will be transferred from the left to the right side.

After the carbon sheets have been intergether with the interleaved carbon sheets will be drawn forward to the platen and into position for printing on the leading web section.

The carbon rolls will then be locked. Preferably, the work-sheet web during the interleaving operation will have been drawn to a position slightly in-advance of the carbon sheets (Figs. 9 and 10) so that after the typing of the first work-sheet section has been completed, the leading ends of the section may be pinched together without pinching the carbons.

With the work-sheets thus pinched together, and secured, the carbon car: rier may be withdrawn rearwardly to its initial position, whereby the carbon sheets will be withdrawn from the completedwork section and will be interleaved with the succeeding section. I obtained by moving the leading ends of the work-sheets and carbon sheets to the same position in advance of the carbon carrier durmg theinterlea'ving operation'and then after the web together with the carbon. sheets has been moved forward into the printing position and with the carbon'spools locked, giving the carbon carrier a rearward throw suf I ficient to draw the'leading ends of the carbon sheets'slightly rearward of the leading ends carbon sheets may be withdrawn from the completedwork section merely by holding the leading edges of the completed section and then pushing the carbon carrier rearward to its initial position,

When it is desired to replace worn carbon areas with fresh printing surfaces it is only necessary to unlock the carbon rolls, draw the'carbon sheets forward a distance suflicient to provide the fresh surfaces, and then tear 01f or detach the leading carbon portion. It

- will be understood that it is not necessary to tear off a carbon length equivalent to the lenghtof a work-sheet section in order to pro:

This same result, may be,

vide fresh carbon areas. Thus, often-times the work-sheet form will be such that it is merely necessary totear off but a very small portion of the carbon sheet in order to move resh carbon areas beneath the forms to be printed. This method of supplying ,fresh carbon areas obviously contributes to an economy of material.

' The arrangement of the carbon rolls is also of advantage when carbons having difierent wearing qualities are being used because it is possible to withdraw any portion of the worn sheets without disturbing the remaining unworn sheets. Thus for example, when hectograph sheets are being used these sheets may be wound into separate rolls so that when portions of the hectographbecome worn the hectograph rolls alone may be unlocked "to permit the worn portions to be detached.

It is to be noted that the carbon carrier and the associated guide members have 'a coniparatively strong construction and yet the construction is very light. The frames 40 and 41 and likewise the supports 38 are of light plate-like form, while the guiding means ,51and 52 have alight rod-like form.
